<p>Heat exchanger systems and methods for controlling airflow cooling are provided. One system includes a bypass pre-cooler (20) having a housing (22), an inlet (36) configured to receive core engine airflow into the housing from one or more aircraft ducts, a heat exchanger (24) within the housing (22) and a bypass section (40) within the housing (22) having an airflow path separate from the heat exchanger (24). The bypass pre-cooler (20) also includes a valve (28) coupled to the inlet (36) and configured to switch airflow between the heat exchanger (24) and the bypass section (40) and an outlet (42) coupled to the heat exchanger (24) and the bypass section (40).</p> |
